Autosizable HVAC Prototype system for Unit Heaters with recirculated airflow most commonly used for heated stairwells or vestibules.

This Unit Heater is multiplex for application to multiple spaces and is autosizable with respect to airflow and coil capacity space heating loads. It has Constant, 2-speed, or Variable recirculation fan control options, and is intentionally set up for a space with no mechanical ventilation (it may have operable windows or no need for separate ventilation, as would be the case for a heated stairwell or vestibule.
